| Sažetak |
In the Linux kernel, the following vulnerability has been resolved:
cachefiles: fix incorrect dentry refcount in cachefiles_cull()
The patch mentioned below changed cachefiles_bury_object() to expect 2
references to the 'rep' dentry. Three of the callers were changed to
use start_removing_dentry() which takes an extra reference so in those
cases the call gets the expected references.
However there is another call to cachefiles_bury_object() in
cachefiles_cull() which did not need to be changed to use
start_removing_dentry() and so was not properly considered.
It still passed the dentry with just one reference so the net result is
that a reference is lost.
To meet the expectations of cachefiles_bury_object(), cachefiles_cull()
must take an extra reference before the call. It will be dropped by
cachefiles_bury_object(). |
